终端能否检测到< Shift-Enter>或< Control-Enter&gt ;？ [英] Can terminals detect <Shift-Enter> or <Control-Enter>?

问题描述

终端是否可以检测⇧Shift + Enter↵或 Ctrl + Enter↵按键？

Is it possible for the terminal to detect ⇧ Shift+Enter↵ or Ctrl+Enter↵ keypresses?

我正在尝试配置vim来执行使用这些序列的键映射，尽管它们在gvim中可以正常工作，但它们似乎无法在任何终端控制台中工作

I am trying to configure vim to do key mappings that use these sequences, and while they work fine in gvim, they don't seem to work in any terminal console.

奇怪的是，尽管在vim中未检测到 Ctrl + Enter↵，但映射了 Enter↵到 Esc 正确映射，但是按 Ctrl + Enter↵的行为类似于Enter↵ ！

The curious thing is that although Ctrl+Enter↵ is not detected in vim, mapping Enter↵ to Esc maps properly, but then pressing Ctrl+Enter↵ behaves like Enter↵!

推荐答案

某些终端在<$ c时发送< NL> $ c>< C-Enter> 被按下。这等效于发送< C-J> 。

Some terminals send <NL> when <C-Enter> is pressed. This is equivalent to sending <C-J>.

要了解您的终端对< Shift-Enter> ，< ; Ctrl-Enter> 和< Enter> ，转到终端，输入< Ctrl-V> （类似于sykora对vim的建议），然后键入您感兴趣的序列。

To find out what your terminal does with <Shift-Enter>, <Ctrl-Enter> and <Enter>, go to your terminal, type <Ctrl-V> (similar to sykora's suggestion for vim), and type in the sequence you're interested in.

使用gnome-terminal，我得到以下信息：

Using gnome-terminal, I get the following:

  <Enter> : ^M
<S-Enter> : ^M
<C-Enter> : <NL>

看着 man ascii 表示 ^ M 给出< CR> 序列。

答案是，这取决于终端，并且有一种简单的检查方法。

The answer is that it depends on the terminal, and there's an easy way to check.
